"Just a Lil Bit" was the third single from 50 Cent's second album, The Massacre. Released in 2005, the single reached number three in the United States, becoming 50 Cent's eighth top-ten single; it also reached number ten in the United Kingdom. The song was produced by Scott Storch.

The music video is set in the Caribbean and follows a thin plot where 50 Cent, as "El Jefe" ("The Boss"), employs three beautiful women to set up his enemies.

The B-side is a live recording of Disco Inferno for AOL Sessions.
